Traditional atomizers include an atomizing disk, a drive motor, a motor seat, an upper bearing seat, a coolant channel structure, and a desulfurization liquid channel structure. At the upper end of the atomizer, the coolant pipeline, the desulfurization liquid pipeline, the lubricating liquid pipeline, the sensor wire pipe, and the power line all need to pass through the upper bearing seat, making the wire pipes led out of the upper bearing seat messy and cumbersome, which makes people dazzled. In the process of assembling the atomizer, it is a big challenge to correctly handle the problem of the wire pipes.

[0003] The above-mentioned traditional atomizer has the following problems: in the process of producing, assembling and repairing the atomizer, especially in the process of maintenance by power plant personnel, it is often the case that due to negligence, the three lead wires of the power cable U, V, and W are inserted into the wrong holes on the upper bearing seat. The problem is not discovered until the upper bearing seat cover is finally installed. The upper bearing seat and the internal bearings need to be disassembled and reinstalled to correct the error. This process is likely to damage the bearing, causing additional economic losses, or affect the bearing accuracy, resulting in a significantly shortened service life. Summary of the invention

The desulfurization liquid outlet channel of the above structure is set, and the desulfurization liquid enters the first feed section 17-2 from the desulfurization liquid through hole. Since the first feed section 17-2 is tangent to the first distribution section 17-3, the desulfurization liquid can enter the first distribution section 17-3 more smoothly. The first distribution port 17-4 is evenly arranged on the inner side of the first distribution section 17-3. In this way, the desulfurization liquid entering the first distribution section 17-3 can evenly enter the first distribution hole 17-1, and then evenly enter the atomizing disk 1; in addition, since the desulfurization liquid is in the first distribution section 17 -3 flows from the first distribution port 17-4 into the first distribution feed hole 17-1, so the flow rate of the desulfurized liquid gradually decreases during the flow in the first distribution section 17-3. By gradually reducing the cross-section of the first distribution section 17-3 from the position connected to the first feed section 17-2, it can be ensured that the desulfurized liquid always maintains a sufficient flow rate during the flow process of the first distribution section 17-3, so that the desulfurized liquid is evenly distributed in the first distribution section 17-3, and then evenly enters the first distribution feed hole 17-1 and reaches the atomizing disk 1.

In this way, the temperature regulating liquid entering the second distribution section 18-3 can evenly enter the second distribution hole 18-1, and then evenly enter the atomizing disk 1; in addition, since the temperature regulating liquid is in the second distribution hole 18-2, the temperature regulating liquid can enter the second distribution hole 18-1. Segment 18-3 flows while entering the second distribution feeding hole 18-1 from the distribution port. Therefore, the flow rate of the temperature regulating liquid gradually decreases during the flow of the second distribution segment 18-3. By gradually reducing the cross-section of the second distribution segment 18-3 from the position connected to the second feed segment 18-2, it can be ensured that the temperature regulating liquid always maintains a sufficient flow rate during the flow process of the second distribution segment 18-3, so that the temperature regulating liquid is evenly distributed in the second distribution segment 18-3, and then evenly enters the second distribution feeding hole 18-1 and reaches the atomizing disk 1.

By setting the above-mentioned cover plate, the plug 13 is set on the top cover, and the external power line is connected and closed by plugging and unplugging the socket and the plug 13. Since the plug 13 is connected to the terminal 8 through an electric wire, when the plug 13 is connected to the power supply, the drive motor 2 can be connected to the external power supply, so that the drive motor 2 drives the atomizer disk 1 to rotate.

[0059] See also Figure 1, and also includes an external shell, the external shell includes a lower shell 14 sleeved on the lower end of the motor base body 3 and an upper shell 15, the upper end of the motor base body 3 and the top cover are both arranged in the upper shell 15.

[0060] See also Figure 1 , and also includes a pressing sleeve 16 arranged in the motor seat body 3, the upper end of the pressing sleeve 16 is pressed against the upper bearing seat 4, and the lower end is pressed against the housing of the drive motor 2. The pressing sleeve 16 is provided with a clearance groove at the position corresponding to the outlet hole. When the pressing sleeve 16 is provided, when the upper bearing seat 4 is installed on the motor seat body 3, the upper bearing seat 4 is pressed against the pressing sleeve 16, and at the same time, the pressing sleeve 16 is pressed against the housing of the drive motor 2, that is, the pressing sleeve 16 plays a role of pressing and fixing the drive motor 2, so that the drive motor 2 is stably and securely installed in the motor seat.

[0061] See also Figure 1-Figure 4 , the working principle of the above atomizer is:

[0062] The assembly process of the atomizer is as follows: first, install the lower bearing in the bearing position corresponding to the lower bearing seat 5, and install the lower bearing seat 5 on the lower end of the motor seat body 3; then, assemble the drive motor 2 into the motor seat body 3, and match the lower end of the motor shaft with the lower bearing, so that the lower end of the motor shaft is installed on the lower bearing seat 5 through the lower bearing; secondly, lead the motor lead out from the wire outlet hole; next, install the upper bearing in the corresponding bearing position on the upper bearing seat 4; finally, install the upper bearing seat 4 on the upper end of the motor seat body 3, and match the upper end of the motor shaft with the upper bearing, so that the upper end of the motor shaft is installed on the upper bearing seat 4 through the upper bearing. During the assembly process, on the one hand, the motor leads are led out from the outlet hole, which is convenient and easy to assemble. Even novice assemblers or other assemblers who are not familiar with the internal structure of the machine can smoothly and correctly assemble the motor leads into place, thereby greatly reducing the assembly time of the atomizer and making it less prone to errors. On the other hand, by setting the outlet hole, the motor leads are led outward from the outlet hole, so that three vertically upward through holes are reduced on the upper bearing seat 4, reducing the complexity of the threading holes in the upper bearing seat 4, and greatly improving the convenience of assemblers to install other wire tubes, thereby effectively avoiding the problem of bearing damage caused by the misalignment of the lead-out wire with the hole position of the upper bearing seat 4, and the need to disassemble the upper bearing seat 4 and the internal bearings many times.

[0063] See also Figure 1-Figure 2, and also includes a supporting structure for mounting the atomizer on the support seat, the supporting structure includes a supporting convex ring 3-5 and a bearing seat 23 arranged on the outer wall of the motor seat body 3, the bearing seat 23 is sleeved on the motor seat body 3, and the upper end of the bearing seat 23 is tightly against the lower end of the supporting convex ring 3-5; when the atomizer is installed on the support seat, the lower end of the bearing seat 23 is arranged on the support plate of the support seat, and is connected to the support plate through a connecting structure. In a thermal power plant, the atomizer is installed on the upper end of the incinerator, specifically, the incinerator is installed on the support seat in the shaft, when assembling the atomizer, the bearing seat 23 is sleeved upward from the lower end of the atomizer, so that the upper end of the bearing seat 23 is tightly against the lower end of the supporting convex ring, thereby mounting the bearing seat 23 on the motor seat body 3. When installing the atomizer on the support seat, adjust the posture of the atomizer so that the axis of the atomizer is in a vertical state, then hoist the atomizer onto the support seat, and make the lower end of the bearing seat 23 fit on the support plate, and finally fix the bearing seat 23 and the support plate through the installation connection structure to complete the installation of the atomizer on the support seat. In the above-mentioned supporting structure, the lower end of the load-bearing seat 23 is attached to the supporting plate, and a connecting structure is arranged between the load-bearing seat 23 and the supporting plate, and the connection between the load-bearing seat 23 and the supporting plate is stable and reliable; since the upper end of the load-bearing seat 23 is tightly against the lower end of the supporting convex ring, the gravity of the entire atomizer is dispersed to the load-bearing seat 23 through the supporting convex ring, that is, the load-bearing seat 23 provides a supporting force to the entire atomizer by supporting the supporting convex ring. In this way, when the atomizer is lifted upward from the vertical shaft of the reaction tower, if the atomizer falls downward due to improper operation of the operator, the atomizer collides with the supporting seat, and the impact force of the falling atomizer is dispersed to the load-bearing seat 23 through the entire circumferential surface of the lower end of the supporting convex ring 3-5. The supporting effect of the load-bearing seat 23 prevents the atomizer from continuing to fall downward, thereby avoiding a high-altitude fall accident.

[0064] See also Figure 1-Figure 2 The bearing seat 23 includes an annular sleeve 23-1 and an annular mounting plate 23-2 arranged on the outer wall of the annular sleeve 23-1; when the atomizer is in the installation state, the upper end surface of the annular sleeve 23-1 is pressed against the lower end surface of the supporting convex ring, and the ground of the annular mounting plate 23-2 is in contact with the supporting plate. The bearing seat 23 of the above structure is provided, the annular sleeve 23-1 is arranged on the motor seat, and is used to support the atomizer, and the annular mounting plate 23-2 increases the contact area between the supporting seat and the supporting plate, so that the atomizer can be more stably installed on the supporting seat.

[0065] See also Figure 1-Figure 2, the annular sleeve 23-1 is provided with a bolt hole, and the motor seat body 3 is provided with a threaded hole corresponding to the bolt hole, and the annular sleeve 23-1 is locked on the motor seat body 3 by a bolt. The above-mentioned bolt hole and threaded hole are provided, and the bolt passes through the bolt hole and cooperates with the threaded hole, so that the bearing seat 23 is connected to the motor seat; it should be emphasized that since the upper end of the bearing seat 23 is tightly against the lower end of the supporting convex ring, the bolt only plays an auxiliary fixing role in the connection between the bearing seat 23 and the motor seat, and does not support the atomizer; the shear force generated when the atomizer falls is borne by the supporting convex ring and the bearing seat 23, thereby ensuring that the bearing seat 23 and the atomizer will not be separated, avoiding the atomizer from falling from a high altitude.

[0066] The above is a preferred embodiment of the present invention, but the embodiment of the present invention is not limited to the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
